New UIM crafting method just discovered?
Due to how many GOTR runs you will do, you will have a lot of points stored for the reward guardian.
The drop rate of pouches from the reward guardian is 1/9 and the abyssal needle drop is a 1/300.
So you can get 2 pouches from the reward pull, use a needle on the guardian to make a abyssal needle then craft a colossal pouch granting 1k crafting.
Drop the pouch, and repeat the process.
The runes are stackable and you can high alch decent items and drop the talismans.
